Password Protected Archive from Console using mcrypt
I'm trying to encrypt some files that will be sent through email. The file is an archive of .sql files. I would like to know what is the best way to use mcrypt to encrypt this file. I see there is many options and unfortunately I don't know what kind of encryption is best nor can I seem to figure out how to decrypt the *.nc file that mcrypt makes. Any tips in the right direction would be great.
